It is good news that the historic Anderton boat lift is to be restored at last. However, I would like to correct a minor inaccuracy (NCE 12 November).
Although it is the only surviving example of this type of structure in England, the Anderton Lift was by no means the first. Five vertical lifts (and two large inclined-plane lifts) were built in Somerset on the Grand Western Canal in the 1830's by the remarkably forward - looking engineer, James Green, whose drawings are in the Institution library.
These structures, which fell into disuse before the Anderton Lift was built, are now being investigated for archaeological restoration. Interested members can view the best preserved site at Nynehead, near Wellington.
